IMPROVEMENT IN ZINC BOARDS FOR ST'OVES.

Specification forming part of Letters Patent N 0. 112,996, dated March 21, 1871.

To all whom it may concern:

Be it known that I, WILLIAM WESTLAKE, of the city of Chicago, in the county of (Jock and State of Illinois, have invented certain new and useful Improvements in Zinc Board for Stoves, of which the following is a full description, reference being had to the accompanyin g drawings making a part of this specification, in which- Figure l is a top view; Fig. 2, a'vertical section; Fig. 3, a bottom view. Fig. 4 illustrates another manner of supporting the top of the board; Fig. 5, an enlarged detail.

The object of my invention is to construct azinc board for stoves better and cheaper than those now in use; and I do this by taking a piece of zinc, either round or oval, as may be desired, and turning down the edge thereof, so as to form a flange, the extreme edge being beaded, and providing a suitable support for the legs of the stove to rest upon.

In the drawings, A represents a piece of zinc, having an ornamental flange, a, the edge of which has a head, I), for strength. This flange may be of any suitable width. I usually make it about one inch wide. under side of A I secure one or more pieces of board, as seen in Fig. 3.

I usually use four pieces, B, of the form shown, thus using but little lumber, and cutting the same with very little waste. These pieces should be thick enough to come out on a line with the outer edge of the flange, furnishing a support for the legs of the stove, and they may be secured in place by means of pieces ofsheet metal 0, soldered to the flange, and tacked to the pieces of board at d.

It is not necessary thatthese wood supports should extend entirely around the interior of the zinc, as shown, though in use it will be found convenient to have the board so con structed.

The head b may be wired, ifdesired, though it will not usually be necessary. This bead Upon the forms a nice finish for the edge of the zinc, and keeps it in place, and presents no points or corners.

Instead of the wood supports B, metal supports 0 may be secured to the under side of the zinc, at the points where the legs stand, and

In the drawings, 0 represents a perforated hollow knob, soldered to A around tral hole mentioned.

The flange and head can be made by machinery.

I do not confine myself to the use of zinc, though this metal is obviously the best.

As zinc boards for stoves are now made the edges of the zinc are bent over and tacked to a rectangular board, the ends of which must be secured against Warping, and it is difficult to make a nice job free from points, and round or oval boards cannot be made without great expense. The wood portion of zinc boards now used is likely to shrink, the zinc becoming uneven.

The zinc board described is free from all these objections, and can be made at less cost than those now in use.

The flange a is continuous, without seam or joint.

What I claim as new is-- As a new article of manufacture, the herein-deseribed zinc board or platform for stoves, consisting of the sheet A, provided with the flange a, and having blocks secured at suitable points underneath for supporting the legs of the stove, substantially. as described.

WILLIAM WESTLAKE.
